3. Set the Cyclic I/O Data Locations in the RMC
In the Project pane, expand the Modules folder, double-click the CPU module, and
choose EtherNet/IP.
In the Outgoing Cyclic I/O Data section, enter the starting location for the Outgoing
Cyclic I/O Data. In our example, verify that the location is the Indirect Data Map Entry
0 Value.
In the Incoming Cyclic I/O Data section, enter the starting address for the
Incoming Cyclic I/O Data. Click the Browse button and browse to the desired RMC
location for the outgoing data. This should be a location in the Indirect Data Map,
the Variable Table, or Command Area as discussed in the Determine I/O Data
Locations in the RMC section above.
For example, the EtherNet/IP Settings Page below shows an RMC150 with the
Outgoing Data coming from the Indirect Data map starting at item 0 and the
Incoming Data going to the Indirect Data starting at item 12.
4. Choose Whether to Use a Sync Register
The Sync Register provides a method for the PLC to synchronize the Input Data and
Output Data. If you will be writing to the Command Area directly or indirectly via
the Indirect Data Map, Delta recommends using the Sync Register.
With a Sync Register, the Incoming Data is not written to the RMC until the Sync
Register change. If you prefer to have the Incoming Data be written whenever any
value in the Incoming Data changes, choose the option to not use a Sync Register.

Configuring the Omron Connection
The following procedures describe setting up an EtherNet/IP I/O connection between an
Omron communication adapter and an RMC using Omron’s Network Configurator
software. These procedures are based off of Network Configurator 3.20. The
corresponding Omron documentation for these procedures is in section 6 (Tag Data Link
Functions) in the Omron EtherNet/IP Units Operational Manual (W465) manual.
1. 1. In CX-Programmer, ensure that your PLC IO Table includes the module with the
EtherNet/IP port, and that the IP settings are configured properly for your network. Be
sure to apply these IO Table settings to the module, restarting the Communication
Adapter if necessary.
2. Start the Network Configurator.
